For making content of the present invention clearer,, the negative pressure wound treating system of transudate volume and viscosity graph of a relation that shows of the present invention is elaborated through concrete embodiment below in conjunction with accompanying drawing.
Referring to Fig. 2, the shown transudate volume in the present embodiment and the negative pressure wound treating system of viscosity graph of a relation comprise: liquid-collecting bottle 5 is used to collect wound fluid; Negative pressure wound therapy equipment 8 comprises negative pressure source 6 and controller 7; The wound external member is used to fill wound and wound closure, comprises wound implant 2, wound closure thing 3, and wound implant 2 is communicated with liquid-collecting bottle 5 through connection tube 4; Liquid-collecting bottle 5 is communicated with negative pressure source 6, for it negative pressure is provided by negative pressure source, and wound fluid is flowed in the liquid-collecting bottle 5; The wound fluid management devices comprises wound fluid volume checkout gear 9 and wound fluid viscosity checkout gear 13; The arithmetic element (not shown), volume and viscosity data according to detection obtains generate a corresponding graph of a relation; Display interface 12, the corresponding relation figure of demonstration volume and viscosity; Volume that said arithmetic element obtains detection and/or viscosity data are mated with preset accordingly alarming value separately respectively;, volume and/viscosity data send alarm signal when reaching preset alarming value; Also comprise an alarm 14, report to the police according to alarm signal.
Wherein, wound fluid volume checkout gear 9 is enclosed within a centrage along on the vertical screw mandrel 10 that extends of liquid-collecting bottle, and the centrage of screw mandrel 10 is vertically parallel with liquid-collecting bottle 5; Wound fluid volume checkout gear 9 comprises: transmitter unit 91 to liquid-collecting bottle 5 launching electromagnetic waves or ultrasonic signal, is arranged on a side of liquid-collecting bottle 5; Receiving element 92; Receive through liquid-collecting bottle 5 refractive electromagnetic wave or ultrasonic signals; Relatively be arranged on the opposite side of liquid-collecting bottle 5 with transmitter unit 91, make it when the position does not have transudate, just to receive here through penetrating refractive electromagnetic wave or ultrasonic signal at liquid-collecting bottle 5; Detect control unit, whether receive electromagnetic wave or ultrasonic signal is judged, if not, judge that then there is wound fluid at place, wound fluid volume checkout gear position according to receiving element.
Wherein, The electromagnetic wave that the long-pending checkout gear of wound liquid body exudate adopts in the present embodiment is an infrared ray; As other embodiment, also can adopt visible light, ultraviolet, laser or other electromagnetic signals, can adopt is ultrasound wave, infrasonic wave or other acoustic signals.
Wherein, wound fluid volume checkout gear 9 suffers restraints on screw mandrel 10 centrage circumferential direction, only can on screw mandrel 10 centerline directions, move; One end of screw mandrel 10 is connected with motor 11, and under the driving of motor 11, screw mandrel 10 moves up and down along screw mandrel 10 centrages thereby drive wound fluid volume device 9 around its centrage rotation, whether liquid-collecting bottle 5 relevant positions is had liquid detect.
Wherein, screw mandrel 10 also can be substituted like in: gear train, belt, the skin wheel any by other drive mechanisms; As long as wound fluid volume checkout gear 9 can be moved in vertical direction with respect to liquid-collecting bottle 5, just can realize detecting the purpose of liquid-collecting bottle 5 relevant position amount of liquid.
Wound fluid volume checkout gear 9 in the present embodiment when motor 11 work, drives wound fluid volume checkout gear 9 through screw mandrel 10 and moves up and down.Receiving element is in the time and can not detecting between infrared signal redirect; Then can confirm that the present position is corresponding to liquid level at this moment through wound fluid volume checkout gear 9; And then, confirm the liquid level of liquid-collecting bottle 5, thereby calculate the amount of wound fluids in the liquid-collecting bottle 5 according to the stroke of motor.
Below the operation principle of the long-pending checkout gear 9 of wound liquid body exudate in the present embodiment is described.
Referring to Fig. 3; Transmitter unit 91 sends infrared ray S1; Liquid-collecting bottle sidewall 51 1 sides through liquid-collecting bottle 5 penetrate refraction entering liquid-collecting bottle interior zone 52; And then penetrate from sidewall 51 opposite sides of liquid-collecting bottle 5, receiving element 92 receives and penetrates the infrared ray S1 that refraction is come, and another part IR is through being reflected into reflection ray S2.
Referring to Fig. 4, the light path sketch map when Fig. 4 does not have wound fluid for relevant position in the liquid-collecting bottle, the infrared ray light path during down in the face of the no wound fluid in liquid-collecting bottle 5 these places between transmitter unit 91, the receiving element 92 does further analysis:
Infrared ray is mapped to liquid-collecting bottle 5 outer surface of outer cover, injects liquid-collecting bottle 5 shells, is mapped to liquid-collecting bottle 5 inner surface of outer cover if α, beta, gamma, θ are respectively, infrared ray and normal angle when injecting liquid-collecting bottle 5 inner chambers.Inject the point of liquid-collecting bottle 5 outer surface of outer cover and penetrate point respectively and the angle that forms between the liquid-collecting bottle 5 section central point lines if δ is an infrared ray from inner surface.If liquid-collecting bottle 5 radiuses are R, wall thickness is h.
If liquid-collecting bottle 5 shell refractive indexs are n1, refractive index is about 1 in the air, by the law of refraction:
Sin α=n1sin β ≈ n1sin γ=sin θ, then α ≈ θ.In like manner can get θ '=α '.θ and θ ' are isosceles triangle two base angles, so θ=θ ', then α=θ=θ '=α '.
Thus; Angle ε is mainly determined by the deflection of infrared ray at 2 circular arc normals of ejaculation point of injecting a little and penetrating from inner surface of liquid-collecting bottle 5 outer surface of outer cover between the infrared ray S13 that then injects the infrared ray S11 of liquid-collecting bottle 5 outer surface of outer cover and penetrate from inner surface, can be similar to writing:
ε＝δ≈h?tanβ/R＝h/R?tan[arcsinα/n1]
The angle of injecting the infrared ray S12 of liquid-collecting bottle 5 inner surfacies and penetrating between the infrared ray S13 of liquid-collecting bottle 5 outer surface of outer cover also is δ.Angle should be 2 ε=2 δ ≈ 2h/Rtan (arcsin α/n1) between infrared ray S11 and infrared ray S13.
When h＜＜R, δ can ignore, the infrared ray S11 that injects liquid-collecting bottle 5 outer surface of outer cover is substantially parallel with the infrared ray S13 that penetrates liquid-collecting bottle 5 outer surface of outer cover.
Therefore, as shown in Figure 4, receiving element 92 is arranged on the same horizontal line with transmitter unit 91, and receiving element can receive through refractive infrared ray, judges and does not have wound fluid here.
In like manner, the infrared ray light path in the time of can transparent wound fluid being arranged to 5 these places of the liquid-collecting bottle between transmitter unit 91, the receiving element 92 does further analysis, referring to Fig. 5, and the index path when Fig. 5 is equipped with wound fluid for corresponding positions in the liquid-collecting bottle:
If the wound fluid refractive index is n2, then by the law of refraction:
sinα＝n2?sinθ＝n2?sinθ’＝sinα’。
Angle ε between the infrared ray S12 that injects the infrared ray S11 of liquid-collecting bottle 5 outer surface of outer cover and penetrate from inner surface:
ε＝(α-θ)+δ＝[α-arcsin(sinα/n2)]+δ≈[α-arcsin(sinα/n2)]+h/Rtan(arcsinα/n1)；
When h＜＜R, δ can ignore, angle ε: ε ≈ α-arcsin (sin α/n2);
Angle should be between infrared ray S11 and infrared ray S13: and 2 ε ≈ 2 [α-arcsin (sin α/n2)];
Example: when α=30 ° are π/6 radians, and hypothesis wound fluid refractive index and water are near, are n2=1.33.Then angle should be between infrared ray S11 and infrared ray S13: 2 ε ≈, 0.276 radian, promptly 15.8 °.
Be that angle can produce about 15.8 ° variation between incident, emergent ray when wound fluid being arranged here in the liquid-collecting bottle 5.Therefore, referring to Fig. 5, receiving element 92 does not receive IR, and therefore, can judge has wound fluid here in the liquid-collecting bottle 5.
Utilize this characteristic; Position through receiving element 92 is provided with; Make it under liquid-collecting bottle 5 no wound fluid situation, to receive emergent ray just; Can't receive this emergent ray and have under the situation of wound fluid, can judge liquid positions in the liquid-collecting bottle 5, and then calculate liquid volumes in the liquid-collecting bottle 5 at liquid-collecting bottle 5.
Arithmetic element also according to the volume and the time of wound fluid, calculates the wound fluid flow, and display interface also optionally shows the wound fluid data on flows.The wound fluid flow can be represented with among milliliters/second (mL/S), ml/min (mL/Min), milliliter/hour (mL/H), liters/second (L/S), liter/minute (L/Min), liter/hour (L/H) any.
In the present embodiment; In liquid-collecting bottle 5, during the position no liquid at wound fluid volume checkout gear 9 place; Make receiving element 92 can receive electromagnetic wave signal or acoustic signals; When there is liquid the position at wound fluid volume checkout gear 9 places, make receiving element 92 can not receive electromagnetic wave signal or acoustic signals; And then when receiving element 92 did not receive electromagnetic wave signal or acoustic signals, the position of judging wound fluid volume checkout gear 9 places was to stagnate liquid is arranged.According to foregoing description, also can confirm that the position at wound fluid volume checkout gear 9 places is to stagnate liquid is arranged with opposite mode.Such as; When electromagnetic wave signal or acoustic signals can pass liquid-collecting bottle 5 and liquid; When there is liquid the position at wound fluid volume checkout gear 9 place, make receiving element 92 can receive electromagnetic wave signal or acoustic signals, in the position at wound fluid volume checkout gear 9 places during no liquid; Make receiving element 92 can not receive electromagnetic wave signal or acoustic signals; Whether receive electromagnetic wave signal or acoustic signals according to receiving element 92 again, the position of judging wound fluid volume checkout gear 9 places is to stagnate liquid is arranged, to realize detecting the purpose of amount of liquid in the liquid-collecting bottle 5.In addition, difference that can also be strong and weak according to the signal of electromagnetic wave signal that receives or acoustic signals, the position of judging wound fluid volume checkout gear 9 places is to stagnate liquid is arranged, or the like.
Wherein, wound fluid viscosity checkout gear 13, the viscosity of detection wound fluid, this wound fluid viscosity checkout gear comprises: pick off, comprise transmitter unit and receiving element, be used for detecting the viscosity signal of wound fluid; Viscosity detects control unit, goes out the viscosity of wound fluid according to the viscosity signal operation that receives.Because electromagnetic wave or acoustic signals that the receiving element of pick off receives are big more; The viscosity of wound fluid is more little; When so wound fluid checkout gear correspondence does not have wound fluid in the position of liquid-collecting bottle; The electromagnetic wave signal value that its receiving element receives is maximum, and this electromagnetic wave signal maximum is corresponding with wound fluid viscosity minima 100; When receiving element does not receive electromagnetic wave signal fully; Electromagnetic wave signal is minimum; This electromagnetic wave signal minima is corresponding with the maximum 100 of wound fluid viscosity; During detection, electromagnetic wave signal value that can actual detected be arrived and maximum and minima contrast can be known the wound fluid viscosity value that it is corresponding.
Wherein, this viscosity detects control unit also goes out wound fluid according to the viscosity signal operation that receives viscosity.Organize the meansigma methodss of viscosity data more in the arithmetic element unit of account time, and viscosity meansigma methods and predefined viscosity grade are mated, draw this viscosity data corresponding grades.Wherein, predefined viscosity grade is: the value of viscosity is divided into high, medium and low Three Estate evaluation in 0～100 scope, and every grade is used a numeral according to its weight, concrete classification such as table 1:
